IP Address Lookup: Find IP Location, ISP and ASN
An IP address lookup takes an IPv4 or IPv6 address and returns public information about the network it belongs to: the approximate location, the internet provider (ISP), the Autonomous System Number (ASN) and the timezone. The WritoryBuzz tool also shows your own public IP automatically. Location is approximate, usually city or region level, and never a street address.
Type any address, click Look Up, or click My IP to check yourself. No signup is needed.

Location accuracy is approximate (city-level). IP geolocation does not reveal an exact physical address.
It points to your provider's network, often in a nearby city. Country is generally dependable. City is approximate. Treat location as a hint. ISP and ASN describe who runs the network, and are the more reliable fields. A VPN changes the result. The lookup shows the VPN server, not you.
What Is an IP Address?
An IP address is a numerical label that identifies a device or network connection so data knows where to go. IPv4 addresses use four numbers separated by dots, such as 192.168.1.1. IPv6 addresses use eight groups of hexadecimal digits separated by colons, such as 2606:4700:4700::1111.
Your public IP is the address the internet sees. Your provider assigns it, and it may be shared by many customers, as is common with mobile networks that use carrier-grade NAT, or change over time.
How to Use the IP Address Lookup Tool
-
1STEP 1 See your own IP. The tool detects your public address on load and shows it at the top. Use Copy My IP to copy it.
-
2STEP 2 Enter any IPv4 or IPv6 address in the box, such as 8.8.8.8 or 1.1.1.1.
-
3STEP 3 Click Look Up. Use the My IP button to reload your own details.
-
4STEP 4 Read the results. Country, region and city, ISP or organisation, ASN and timezone.
-
5STEP 5 Try the examples below the box to see how results look for well-known addresses.
What Data an IP Lookup Returns
| Field | What it means | How far to trust it |
|---|---|---|
| Country | Country where the address block is registered or mapped | Generally dependable |
| City and region | The approximate location of the network block | Approximate. City-level accuracy varies a lot. |
| ISP or organisation | The provider or organisation that holds the address block | Usually reliable |
| ASN | The Autonomous System Number, the identifier of the network the address belongs to | Exact for the network it names |
| Timezone | The IANA timezone linked to the mapped location | Follows the location, so as reliable as the location |
An IP address lookup, also called IP geolocation, maps an IP address to a country, region, ISP and network using databases built from registry data and other sources. Location is an estimate, not a physical address.
How Accurate Is IP Geolocation?
There is no single master map of IP addresses to places. Lookup services build databases from regional internet registry records, routing data and other sources, then estimate a location. Registry records say who holds a block, not where each device sits.
That is why accuracy depends on the type of connection:
- Country level is usually right.
- City level can be right, off by a neighbouring city or off by a lot. Mobile networks often route traffic through a regional gateway far from the phone.
- Large organisations and VPNs can show the location of a head office or a server, not the user.
- Different tools can disagree because they use different data sources. Two lookups giving two nearby cities is normal.
The tool relies on third-party data, so it inherits these limits. It also cannot tell you whether an address is currently in use by a specific person.
Public vs Private IP Addresses
A public IP can be reached over the internet. A private IP is used inside a local network and is not routable on the public internet. Private ranges are defined in RFC 1918:
| Range | Address block | Typical use |
|---|---|---|
| 10.0.0.0 to 10.255.255.255 | 10.0.0.0/8 | Large organisations and cloud networks |
| 172.16.0.0 to 172.31.255.255 | 172.16.0.0/12 | Medium networks and containers |
| 192.168.0.0 to 192.168.255.255 | 192.168.0.0/16 | Home routers and small offices |
If you look up a private address like 192.168.1.1, there is nothing to find. It exists in millions of separate home networks.
IPv4 vs IPv6
IPv4 uses 32-bit addresses, giving about 4.3 billion in total. The central pool of free IPv4 blocks ran out when IANA allocated its last blocks in February 2011. IPv6 uses 128-bit addresses, a vastly larger space designed to end the shortage. Most devices and networks now run both, which is called dual-stack. If your device has both, you may see an IPv4 address on one site and an IPv6 address on another.
What Is an ASN?
An Autonomous System Number identifies a network or group of networks run by one organisation under a single routing policy. Internet routing uses the Border Gateway Protocol (BGP) to exchange routes between autonomous systems. The ASN tells you which organisation, such as an ISP, a cloud host or a CDN, controls the address block.
What You Can Use an IP Lookup For
- Check your own public IP before setting up remote access, a firewall rule or a service that needs an allow-list.
- Confirm a VPN works. Look up your IP with the VPN on and off. The country and ISP should change.
- Investigate suspicious traffic in logs by checking which network a visit came from.
- Check where a site is hosted by looking up its A record, which you can find with the DNS Lookup.
- Understand analytics. Location in your analytics is usually derived from IP geolocation, which explains its limits.
- Support and troubleshooting. Tell a helpdesk your public IP so they can find your connection in server logs.
Common Mistakes and Misconceptions
- "They can find my house." An IP lookup cannot. Only your ISP can link an address to an account, and normally only through legal process.
- Trusting city results. City is an estimate. Do not use it to make decisions about a person.
- Treating a private IP as a location. 192.168.x.x does not identify anything.
- Assuming one address means one person. Households, offices and mobile networks share addresses.
- Blocking by country only. Location data can be wrong and VPN users can hide.
Honest Limits of This Tool
- Location and network details come from a third-party service, so they are only as accurate as that service's data.
- The tool does not give a street address, a name or any personal details, by design and by the nature of the data.
- It does not check whether an IP is blacklisted, a proxy or malicious.
- It is not a WHOIS tool, so it will not show the full registration record for an address block.
- If a lookup fails, the free third-party service may be temporarily unavailable or rate limited.
Privacy
The tool runs from your browser. It calls ipify.org to detect your public IP and ipwho.is to fetch details, and the page states that neither request passes through WritoryBuzz servers and that WritoryBuzz does not log or store your IP. Because the requests go straight to those third-party services, they necessarily see your IP address and the address you look up, under their own privacy policies.

Frequently Asked Questions
What is an IP address lookup?
An IP address lookup returns public information about an IP address, including approximate location, ISP, ASN and timezone. It shows where the network is, not where a person lives.
Can an IP address reveal my exact home address?
No. A lookup shows the approximate location of your provider's network, usually at city or region level. It does not reveal your street address or your name.
How accurate is IP geolocation?
Country is generally dependable. City is approximate and can be wrong, especially on mobile networks and VPNs. Treat it as a hint, not a fact.
How do I find my public IP address?
Open this tool. It detects and shows your public IP automatically, and you can copy it with one click.
What is the difference between IPv4 and IPv6?
IPv4 uses 32-bit addresses with about 4.3 billion possible values, and the free pool ran out in 2011. IPv6 uses 128-bit addresses with a vastly larger pool. Most devices use both.
What is an ASN?
An Autonomous System Number identifies a network run by one organisation and is used by the BGP routing protocol. It shows which organisation controls an IP block.
How does a VPN affect IP lookup results?
A VPN routes your traffic through a server elsewhere, so a lookup shows the VPN server's location and provider instead of yours.
Why does my IP show a different city?
Geolocation databases estimate location. Your provider may route traffic through a regional gateway in another city, and different services use different data.
Is this IP lookup tool free?
Yes. It is free and needs no signup. It uses two free third-party services to get its data. Look up your IP address now and see what the internet can learn from it.
